2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: eip1.u-ga.fr, eip2.u-ga.fr.

#6
!

NS sets differ

The nameservers at the parent and in the zone should be the same. Only in the zone: soleil.uvsq.fr. eip1.u-ga.fr, eip2.u-ga.fr, soleil.uvsq.fr report NS eip1.u-ga.fr eip2.u-ga.fr soleil.uvsq.fr.

#7
✓ No glue needed #8

All nameservers are outside the zone, so no glue records are needed.
✓ All names resolve #9

Every nameserver name has an address and is not an alias.
✓ Nameservers in different networks #10

The nameservers are spread over 3 IPv4 /24s and 2 IPv6 /48s.
✓ 2 autonomous systems #11

The nameservers are spread over: AS1942 (FR-TIGRE - Renater, EU): 1 address; AS2200 (FR-RENATER - Renater, FR): 4 addresses.
i

All nameserver names under .fr

All nameserver names are under one TLD, so a problem with that TLD also makes the nameservers unreachable. Some operators use names under two TLDs for extra resilience.

#12
i

Partly IPv6

These nameservers have no IPv6 address: soleil.uvsq.fr.
